Step into the rugged beauty of Japan's high mountains for an unforgettable endurance challenge. The Hotaka and Tone races, held on the majestic slopes of Mt. Tanigawa, offer runners two distinct courses: the grueling 138km HOTAKA course and the challenging 77km TONE route. Both routes feature a cumulative elevation gain exceeding 8,000 meters, testing participants' physical limits as well as their decision-making skills in unpredictable mountain conditions. The race takes place amidst pristine forests and alpine meadows, where runners will encounter steep ascents, technical descents, and breathtaking views at every turn. The terrain is both demanding and rewarding, with each step revealing the untamed beauty of Japan's natural wilderness. As you navigate through this challenging landscape, you'll find yourself immersed in a race that truly pushes your limits as an athlete. Registration fees vary depending on when you sign up: for the 138km HOTAKA course, early registration is set at ¥42,000; for the 77km TONE route, participants can register before the event day for ¥30,000 or opt for same-day entry at a slightly higher rate of ¥33,000. This race isn't just about reaching the finish line—it's an invitation to experience the raw power and beauty of nature in one of Japan’s most spectacular mountain ranges. For those seeking adventure beyond the usual, this event promises an authentic high-mountain running experience that will leave a lasting impression on all who dare to take part.
